Hi all,
I need help designing a special circuit.
The circuit is basically should monitor a current to the load and break the supply once the load consumes more than maximum current.
The circuit should retry to connect to the load after programmable time period.
I've manage to build only a partial circuit - it monitors the current, when overcurrent occures - it disconnects the load, but never restarts, so the circuit is basically latched and can be released only when I disconnect the supply voltage.
is there any other way to build such a circuit?
I found a popular "emiter follower current limiter design", but the MOSFET gets very hot and can't be use with high power loads.
I have to use only discrete components, no ICs (this is the basic demand)
